Hello Martin and all,

first i have to report that thunderbird52 shows the same or similar
issue and is also crashing when built from pkgsrc_2022Q4.

I now have built the debug symbol version of firefox52 as instructed.
I get an error displayed from gdb referring to python, but it seems it
runs anyway:

+m ./firefox
root@localhost:/usr/pkgsrc/www/firefox52/work/build/dist/bin#

Then i run it and get the following result:
